cient and durable construction, composed of few parts, and capable of being cheaply manufactured, and in which the rollers will automatically return to central or normal position.

My invention consists in connection with an upper shoe or bearing plate xedly secured to the body bolster, of a lower bearing plate tixedly secured to the truck bolster,

and provided with double or reversely inclined sides, a pair of antifriction rollers interposed between the upper shoe and lower bearing plate, a pair of double inclined or wedging followers having trunnions engaging the rollers and inclined faces engaging the inclined side wallsl of the lower bearing plate, and springs in the rollers and between the followers.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and more par ticularly specified in the claims. p In'the accompanying drawing forming a part of this specification, Figure l is a front' elevation showing, a railway car truck and body bolster furnished with my improved roller side bearings. Fig-2 is a detail side elevation of one of the roller side bearings, partly in section on line 2-2 of Fig. 8. Fig. 3 is ay plan View partly in horizontal section online 3 3 of Fig. 2.- Fig. 4 is a vertical cross section online 4-4 of Fig. 3 and Fig. 5 is a detail perspective view of one of the Wedge faced followers.

In the drawing, A. represents the body bolster, B the truck bolster of a railway car, C the upper bearing plateor shoe fiXedly secured to the body bolster by suitable bolts C1, D the lower bearing plate iXedly secured by bolts D to' the truck bolster, E E

y anti-friction rollers between the upper and lower beariner plates, F the wedge faced followers and the springs.

4The lower bearing plateD is preferably furnished with a separate piece or removable wearing plate or4 tread piece d of steel or other suitable metal for the rollers to roll upon, 'the same fitting within a suitable re- 60 cess d1 formed by surrounding flanges Z2 and shoulders d3 to confine the .removable wearing pla-te in position. The lower bear ingplate D is provided with double inclined or wedging side walls d4, the sidewalls d* d* f converging from the middle portion of the bearing plate D toward each end. The side' walls cl1 d* are also preferably upwardly convergingso that when the followers F F are in position, they will slightly compress the springs- G or put them under an initial tension. 'The lower bearing plate D is also provided with a top web or flange d5, the edgescl6 of which serve as guides for thel ends of the rollers E to keep the rollers i 7 5v position lengthwise.

The rollers E arepreferably two in number and cylindrical in form, and are each furnished with a large central bore or openingE1 to receive the springs G and the hubs 80 or studs f of the followers F.

The followers F each have two hubs or studs f f, one fitting within one end of cach of the rollersE. Each of the studs f is preferably provided Hangs f1 to receive and support the end of the spring-G. Each of the followers F has double or reversely inclined we ing faces f2 adapted to fit against the dou le or reversely inclined side walls d* of the lower bearing plate D and thus cause the springs to be compressed when the rollers travel in either direction on the lower bearing plate. The lower` bearing plate D on each side of its tread/ or wearing plate d hasopenings I)2 to permit the free' escape of dirt or cindcrs. The followers F- with their studs engaging the rollers serve both as spacing devices for keeping the rollers properly spaced and in alinement and also as followers toreturn the rollers to their normal position after e'ach swinging movement ofthe truck and body bolsters in respect to each other. The end walls d7 of the lower bearing plate D are preferably curved on the inside in conformity with the curvature of the rollers asvindicated at ds on Fig. 2 of the drawing.

I claim l; In a roller side bearing, the combination with an upper bearing plate fixed to wit-h a hollow rim or 85 the body bolster, of a lower bearing plate fixed to the truck bolster and having reversely inclined side walls converging from the middle toward each end, rollers interposed between said bearing plates, followers .engaging said rollers and having reversely inclined faces en aging said reversely inclined side walls o said lower bearing plate, and springs within the rollers interposed between said followers, substantially as specied. e

'2. In a roller side bearing, the combination of a bearing plate havin inclined side walls, of followers having inc ined faces engagin said side walls, a roller engaging said ollowers and a spring interposed be- ;lween said followers, substantially as speci- 8. In a roller side bearing, the combination of a bearing plate having inclined side walls, of followers having inclined faces engagin' said side walls, a roller engaging said ollowers and a spring interposed between said followers, said spring being within the roller, substantially as specified.

Il. ln a roller side bearing, the combination of a bearing plate having inclined side walls, of followers having inclined faces engagino -said side walls, a roller engaging said followers and a sprinr interposed be'- tween' said followers, said spring being within the roller, and saidfollowers having studs fitting within the ends of the roller, substantially as specified.

5. In a roller side bearing, the combination with a bearing plate having side walls converging from the middle toward each end, of followers engaging said converging side walls, rollers engaging said followers and springs within thc rollers and between the followers, substantially as specified.

6. ln a roller side bearing, the combination with a bearing plate having side walls converging from the middle toward each end, of followers engagingsaid converging side walls, rollers engagin said followers and springs within the rolfers and between the followers, and an upper bearing plate4 ngaging thefA rollers, substantially as speci- 7, n a'roller bearing, the combination with a bearinglplate, having inclined side` walls converging from the middle toward each end, of followers engaging said con` verging sidewalls a roller enga 'n said followers and a spring between salgd fllowers, substantially as specified.

8. In a roller bearing, the combination lwith a bearing plate having inclined side walls converging from the middle toward each end, of followers engaging said converging side walls, a roller engaging said followers and a spring between said folloilvers, said spring being within thc roller, substantially as specified.

9. In a roller bearing, the combination with a bearing plate having inclined side walls converging from the middle toward each end, of followers engaging said converging side walls, a roller engaging said followers and a spring between said followers, said spring being within the roller, and an upper bearing plate engaging the rollers, substantially as specified."

lO. In a roller bearing, the combination with a bearing plate, of a hollow roller rolling on said plate, and a spring within the roller to return it to normal position, and a follower having a stud fitting within said roller and against which the spring coacts, substantially as specified.

ll. In a roller bearing, the combination with a bearing plate, of a hollow roller rolling on said plate, a spring within the roller to return it to normal position, and a follower against which the spring acts, substantially as specified.`

l2. ln aroller bearing, the combination with a bearing plate, of a hollow roller rolling on said plate, a spring within the roller to return it to normal. position, and a follower against which the spring acts, said bearing plate having an inclined face against which said follower acts, substantially specified.

13. In a roller bearing, the combination with a bearing plate, having inclined side walls converging from the middle toward cach end, of followers engaging said converging side walls, a roller engaging said followers and a spring between said followers, said side walls of the bearing plate being also upwardly converging andv oper- -wardly inclined, substantially as specified.
